Answer:
Step-by-step explanation:
First and foremost, a root is the same thing as a zero. It's called a zero because when x is equal to -1/4 (as it is here), y = 0. Where y = 0 is the x-axis. So if a quadratic has a 0 of -1/4, that is where the graph of the parabola goes through the x-axis.
If your quadratic has a zero of -1/4, that means that when y = 0, x = -1/4. Again, because this is a zero of the quadratic, then we can write it in factor form by setting x = -1/4 equal to 0. Do that like this:
If x = -1/4, then x + 1/4 = 0 and the factor is (x + 1/4) However, we do not want to leave that as a fraction. Take care of the fraction when it is set to equal 0:
and multiply everything by 4:
and simplify to
4x + 1 = 0 and the factor is
(4x + 1).
Do the same with the 3/2: If
, then
. Multiply everything by 2 to get:
to give you
2x - 3 = 0 and the factor is
(2x - 3).
FOIL those 2 factors together to get
which simplifies to
![8x^2-10x-3=0](https://tex.z-dn.net/?f=8x%5E2-10x-3%3D0)
Now set it back equal to y and you're done!
50%..Or 50/100 This is because you have the option of 1-4 and since 1 & 3 are odd numbers and thats 2 of your 4 numbers you would have 50%
Answer: Okay so let's try to find the amount of money needed to buy 1 lb. Therefore, let's divide the fraction by 14.
Then we'll divide both the numerator and denominator by 14.
÷
Then we simplify and get:
14÷14=1 2.99÷14=.2135 We can round that to .21
The unit rate for each pound would be 1:.21
I don't know if that helped, but yeah. :)
